Animating with images

[andrioid]

After adventuring with code-snippets, using shiki I'd like to create animated webp files. But, as far as I can tell; renderAnimation() doesn't accept "persistedImages" like render() does.

The only animation examples, I've found are in the benchmark code.

I already have some of it working, but I'd love to add images too!

The ImageResponse API was confusing me. Obviously, I pass the persistedImages to the renderer constructor to make it available to renderer.renderAnimation(). Worked like a charm!

animation is still in the very beginning stage, and there's a lot of space to improve for both performance and tooling.

I think an abstraction like an AnimationResponse API would make the experience much better.

AnimationResponse would be nice. It it possible to output mp4 without bringing in ffmpeg, or is that completely out of scope?

[kane50613]

This is out of scope unfortunately, as it's designed to be compact. Batch rendering with raw format and passing the RGBA buffer to FFmpeg input stream could be a feasible option.

This could actually be fast since no png/webp encoding required. I actually want to test this out and post on twitter lol.

I'd love to see an example of that
